CARBON FIBER REINFORCEMENT BAR AND MANUFACTURING PROCESS THEREFOR, AND CONTINUOUS MANUFACTURING APPARATUS AND CONCRETE STRUCTURE

摘要

A carbon fiber reinforcement bar (1) is obtained by: applying fine particles which comprise silicon dioxide as a main component to the surface of carbon fibers (1c) to coat the surface with the fine particles; applying a cement paste to the surface of the carbon fibers which has been coated with the fine particles; and solidifying the whole of the resulting composite. When laid in a concrete structure as a substitute for an iron reinforcement bar, the carbon fiber reinforcement bar (1) exhibits a high force transmission efficiency and a high reinforcing effect.
